Abstract: 2.1 In a known lubrication system for an internal combustion engine, the lubricating oil is passed from a lubricating-oil pump through a heat exchanger or through a bypass line to the heat exchanger. Oil released by a pressure-limiting valve downstream of the lubricating-oil pump is released directly into the oil pan and, particularly at full load, leads to high oil temperatures in the oil pan. 
<??>2.2 According to the invention, a differential pressure valve 6 is to be provided, which releases lubricating oil into the bypass line 5b bypassing the lubricating-oil heat exchanger 7. Connected downstream of this differential pressure valve 6 at a suitable point in the internal combustion engine is a pressure-maintaining valve 10 which maintains the oil pressure approximately constant while the internal combustion engine is running and protects the lubricating-oil pump 3 from excessive pressure when starting a cold engine.

Abstract: An internal worm drive suitable for use for or with a dampening roller in a lithographic dampening system has a worm gear and a substantially hollow tubular worm with an outer surface and an inner surface. The inner surface has at least one internal worm thread mating the worm gear. The axis of the worm gear is substantially perpendicular to the longitudinal axis of the tubular worm. Utilizing the tubular worm with the threaded internal surface in conjunction with the mating worm gear is an oscillating roller assembly suitable for use as a dampening roller in lithographic presses. The oscillating roller assembly has a shaft, and a bearing unit mounted along the shaft. A worm gear having a plurality of teeth is contained in a slotted space in the bearing unit and the shaft such that the rotational axis of the worm gear is substantially perpendicular to the longitudinal axis of the bearing unit and the shaft. The slotted space has first and second opposite longitudinal ends within the shaft. A pair of substantially coaxial eccentric cams are integrally affixed to opposite surfaces of the worm gear. The cams alternately engage the shaft at the opposite ends of the slotted space. A roller shell having at least one internal thread is circumferentially mounted around the bearing unit such that its internal thread engages the teeth of the worm gear. Rotation of the roller shell causes the worm gear to rotate, thereby causing the cams to alternately engage the shaft at the opposite ends of the slotted space, thereby causing the bearing unit and roller shell to oscillate back and forth along the shaft.

Abstract: A thermochemical scarfing method and apparatus are disclosed which allows a greater diagonal standoff distance from the metal workpiece during preheating. The method includes preheating the end of the metal workpiece, and then scarfing the workpiece by directing a scarfing oxygen stream onto the workpiece at an acute angle and while moving the workpiece past the oxygen outlet port. The preheating step includes generating a high speed stream of oxidizing gas and a concentric stream of fuel gas coaxially about the central stream, so that the momentum of the central stream is maintained. As a result, the effective flame heating distance may be extended, and the manifold and head assembly which supports the preheating gas nozzles may be moved back from the workpiece a significant standoff distance so as to avoid damage from dislodged molten metal slag.

Title: Novel catalysts for preparation of polyurethanes
Inventor: GRIER LAURA ANN
IPC: C08G18/16
Filed: 1992-10-09
Abstract: Novel catalyst compositions comprising complexes of tin (IV) salts and amine compounds are used to prepare polyurethanes, polyureas, polycarbodiimides and polyisocyanurates. The complexes, which preferably employ primary amines, allow delay of gelation until they dissociate under certain reaction conditions. The complexes can be prepared neat, or in situ in an active hydrogen containing formulation component. The complexes serve to delay gelation of the formulation because they are relatively stable to moisture and will predictably dissociate upon heating, either as a result of the exothermic nature of the reaction being catalyzed or with application of an external heat source. The catalyst compositions are particularly useful for preparation of carpet underlay and in other applications requiring significant delay prior to gelation.

Abstract: The fabrication of rough Si surfaces with control of the roughness density, roughness length scale, and morphology on a nanometer scale is disclosed using 1) a low pressure chemical vapor deposition (CVD) process, typically in the 1 - 5 mTorr range, and 2) initial surface conditions and operating parameters such that initial growth is nucleation-controlled, e.g., using a thermal SiO₂ surface which is relatively unreactive to SiH₄ at an operating temperature below about 700°C, and typically in the range of 500 - 600°C. This broad temperature window enhances the feasibility of manufacturing rough silicon surfaces with broad applications. Further, various methods are presented for achieving surface pretreatment to control the size and density of the initial nuclei preparatory to the performance of the foregoing fabrication process. In addition, a method is disclosed for producing on a substrate surface, directly and in-situ, a pattern of submicrometer sized dots such that the dot center surface density and the total dot surface area coverage can be precisely controlled, using the features of the fabrication process with additional steps to achieve the desired dots. 
     Particular applications include fabricating rough Si surfaces as (1) electrodes for high capacitance density structures for high density DRAM and (2) as substrates for low-stiction magnetic disks.

Abstract: A multi-color, electrostatic, laser printing system (10) employs a method for enhancing color representations at boundaries of pixels with different colors. The system employs a charged electrostatic surface that is selectively discharged by application of a modulated laser beam. The system performs the steps of: identifying a pixel (80) of a first color that bounds a pixel (86) of a second color, the first color being a secondary color; decreasing applied laser power to the electrostatic surface at the secondary color pixel site (86) in the process of applying underprint (84) and overprint (82) toners to produce the secondary color; and inhibiting the decrease of applied laser power when applying the overprint toner (82) if the second color pixel (86) is a primary color that is the same as the color of the overprint toner (82) of the secondary color pixel (86). A similar inhibition action occurs when an isolated primary color pixel (91) or a thin pixel line (91,92,93) is found so as to assure proper development.
